I tested with a more recent model B (512 Mb without polyfuse) and that's great !
Without USB hub I have 4.95V with Camera + USB WiFi !!

Thanks for your answers RaTTuS, I'll try to find a good little hub for my project !
My battery should be able to power the Pi and the hub at the same time or use a second battery for the hub (I really need wireless things, because that's a robot ).

Btw, if I'm using (I can have one for free) a 512MB model, do you think that could solve it the problem ? Instead of soldering on the board to bypass fuse.. About the battery, that's the best I saw, a TeckNet® PowerBank 15000mAh (and I have also a TeckNet® PowerBank 7000mAh). About the measurement, ...

Hi RaTTuS, I have the "0002" revision, model B, with 256MB (2 USB ports). The Pi kernel + apps are less than 2 months old so I don't think that could be the problem (3.12.24+ #694).. I also tried with another battery and that is the same.. I can also say that actually, if I'm plugging the USB WiFi a...

Hi, first, I'm sorry if my question is not in the right place, I'm not sure about it.. I'm using a RPi model B / Rev1 with official RPi camera and TP-LINK WN725N USB WiFi adapter directly connected to the Pi. I'm using an external battery which gives 1A or 2.1A. Actually I'm using 1A (but if you tel...

I tried to format the SD card and start from scratch but I had input/output errors sometimes..
So, I tried another one and actually that is working, so the problem is the SD card !

Thanks for your help !

My SD card should be 1 year old maybe, but not used often..

If the problem is from SD, is it possible to clone it to another one, and keeping the system as is ?

Hi, I was using the Raspberry PI (installing Pi-blaster exactly (note that I have Servoblaster too, if that can help)), rebooting it and now it won't boot up.. I've done a "fsck" for the ext4 partition and that fixed lots of things ! But that didn't solve the problem. When the Pi is starting, I have...

Right, I'll try it, but I really don't think that this is the problem..
I'll let you know !

EDIT: mikronauts -> That solved the problem, that was the calibrate which was buggy.. Thanks a lot !

Wow, fast answers, thanks :) ! My servo is DF05SR . @mikronauts: I have a hole in the servo which should be a potentiometer yes, but I don't know how to calibrate it.. And please note that the servo can work normally 2min without any problem, and starting to bug after that amount of time so I'm not ...

Hi, I'm facing to a rotation bug in ServoBlaster.. I'm using these values: 1500us : Idle 1530us : Pulse left 1480us : Pulse right For example : echo 1=1500us > /dev/servoblaster BUT, my problem is the (continuous) servo which rotates itself sometimes.. I mean, I make it to rotate to the right, I sto...

Hi !

A little question about the process.
Is the PI the Group owner in the Wifi-Direct scenario ?
